Description
Technical field
The disclosure relates to therein monitors individual method and system by the transportation monitor.The transportation monitor refers to any patient-monitoring unit that is used in hospital between the delivery period or monitors the patient between hospital when the patient moves in this article.The disclosure also relates to the actual shipment monitor and is used for the auxiliary unit of monitor.
Background technology
The quite complicated measurement equipment (set-up) that the state of monitoring patient in hospital requires accurate monitoring device and has a plurality of sensing elements that are attached to the patient.For in addition during transportation provide and do not have to interrupt monitoring, patient in hospital can be connected to the what is called transportation monitor that is attached to patient's sick bed.The transportation monitor allows the patient to move to another care area or move between hospital from a care area in hospital, and can during transportation not lose any monitoring information from the patient.As patient not in transit the time, the transportation monitor can be connected to central patient monitor, and central patient monitor is positioned at the nursing staff and can be easy to from the zone of its tracking screen patient's states.Connection between two monitors can realize by private cable or by hospital network, but this connection also can be wireless point-to-point connection.When the patient will be moved to new care area, the transportation monitor disconnected from central patient monitor, and during transportation, the transportation monitor is monitored the patient as independent monitor.In new care area, the transportation monitor can be connected to the central patient monitor in that zone once more or reconnect to hospital network.
The notion that the transportation monitor is used with central patient monitor is popular and general, because can reduce required wiring total amount.This is that and unit cable is enough to the transportation monitor is connected to the central monitoring device because the cable that a plurality of sensing elements are connected to actual measurement equipment remains shortly as far as possible.The transportation monitor can be equipped with heterogeneity and/or ability.For example, transportation monitor is configurable to have display unit so that show multiple information to the user, and another transportation monitor can only be collected patient data, and display result or even do not handle collected initial data not.That is to say that monitoring result can only show on the screen of central patient monitor.
A shortcoming relevant with standard transportation monitor is that some hospital care district, particularly MRI (nuclear magnetic resonance) chamber requires special installation, and is out-of-bounds for standard transportation monitor therefore.The assembly of MRI environmental requirement particular design and shielding, so that tolerate related highfield, and therefore standard transportation monitor can't be worked near the MRI device.In addition, standard transportation monitor trends towards transmitting RF and disturbs, and this interference may make pseudo-shadow be present on the MRI image.The monitor of MRI compatibility also should comprise minimum ferrous metal, and it is minimum that the captivation that makes magnetic field thus and produced is reduced to.
Therefore, the patient monitor of MRI compatibility is current to be the device of particular design, and they are because desired special nature and cause expensive and only be used for the MRI environment.If the patient is carried out the MRI imaging, if will monitor the patient during the MRI process, then standard transportation monitor does not provide and does not have the monitoring of interruption, and need replace with the monitor of MRI compatibility.But, the change monitor be trouble and need the too much time, all the more so when particularly considering quite rapidly the MRI imaging process.
Summary of the invention

The specific embodiment
With reference to Fig. 1, patient monitoring system 10 comprises: the transportation monitor 11 that typically is built up in bedside, and set up away from the central patient monitor 12 of object 13 to be monitored, central patient monitor 12 is positioned at the position that the nursing staff can come the surveillanced object state from the screen of central patient monitor.The transportation monitor is collected physiological data from object, and sends data to central patient monitor.
Described transportation monitor is similar to standard transportation monitor, and the accurate transportation of image scale monitor is operated like that.But this is only applicable to transport the normal running of monitor 11.In other words, in normal running, the transportation monitor is incompatible with harsh MRI environment, and can not use near the MRI device.In order to make the transportation monitor become the MRI compatibility, this transportation monitor is equipped with special manipulation mode, in this pattern, does not shield and other special nature of the monitor of routine MRI compatibility even it is equipped with, and it also can operate in the MRI environment.This discusses in conjunction with Fig. 2 below.
The transportation monitor obtains a plurality of physiological signals 15 from object usually, and one of them physiological signal is measured passage corresponding to one.Physiological signal typically comprises the signal of some types, such as ECG, EEG, blood pressure and plethysmographic signal.Based on the original real-time physiological signal data that obtains from object, can determine a plurality of physiological parameters.Physiological parameter refers to the variable that is calculated by the one or more Wave data from the physiological signal of object acquisition at this paper.If physiological parameter draws from the physiological signal more than, that is, physiological parameter draws from the measurement passage more than, and then described physiological signal has identical signal type usually.Therefore, physiological parameter also can be illustrated in upward definite waveshape signal value of predefined time cycle, although the parameter of the uniqueness that physiological parameter draws from one or more measurement passages typically is such as heart rate that draws from the ECG signal or the SPO2 value that draws from plethysmographic signal.Can be to the one or more alarm limits of each signal parameter assignment, so that when parameter meets or exceeds alarm limits, warn the nursing staff.
The transportation monitor can be connected to central patient monitor in a number of ways, and connected mode for example depends on the position of central patient monitor 12.For example, if two monitors close enough each other, then they can be connected to each other by private cable 16.But the connection 17 between two terminals also can be wireless connections or realize by hospital network 18.The transportation monitor is typically determined the physiological parameter from object, and parameter is sent to central patient monitor.But also possible is that the data that central patient monitor is collected based on the transportation monitor are determined new physiological parameter.Under an extreme case, the transportation monitor is only collected initial data and is sent it to central patient monitor.Therefore, the level of ability of transportation monitor may change, and therefore the task sharing between transportation monitor and central patient monitor also may change.In any case a significant advantage of all transportation monitors is that they reduce required wiring total amount, this is because sensor cable 19 keeps short.
Between the delivery period, transport monitor and operate in hospital at object as the independent monitor of collecting physiological data from object.During transportation the data of collecting from object can be sent to the new central patient monitor that the transportation monitor connects in new care area.
As mentioned above, transportation monitor 11 is equipped with special manipulation mode so that it is the MRI compatibility.Fig. 2 illustrates the example of the selection of the operator scheme in the transportation monitor.The operator scheme of transportation monitor depends on whether there is the highfield, that is, whether monitor is near MRI device (perhaps producing another device of highfield).The detection in magnetic field can be automatic.That is to say whether transportation monitor sensing serially exists highfield (step 21).When not detecting the highfield, the transportation monitor is limited in its normal manipulation mode, and in this pattern, the transportation monitor is operated (step 22 and 23) as standard transportation monitor.But if the transportation monitor detects highfield ( step 22 and 24/ "Yes") during normal manipulation mode, then monitor enters MRI operator scheme (step 25) by the magnetic assembly unit that forbidding uses in normal manipulation mode.The magnetic assembly unit refers to the unit that its operation relies on magnetic in this article.This type of unit typically comprises the assembly that comprises ferromagnetic material.In the highfield of MRI device, this type of material is saturated, and if the unit be not damaged, then the high external magnetic field that is produced by the MRI device at least causes malfunctioning.For example, in standard transportation monitor, this class component typically is used for blood pressure measurement.Except forbidding magnetic assembly unit, the transportation monitor can will be replaced unit come into operation (step 26).That is to say, replace using inner magnetic assembly unit, the transportation monitor can use in the MRI operator scheme replaces the unit.
As long as the transportation monitor detects the highfield and just remains on the MRI operator scheme, and (step 22/ "No") turns back to normal manipulation mode when the highfield no longer exists.In normal manipulation mode, the magnetic assembly unit comes into operation once more, and the transportation monitor is as operating with the incompatible standard monitor of MRI environment.In the persistent period of MRI process, the transportation monitor may thereby be converted or may convert to voluntarily the monitor of MRI compatibility, and this monitor is operated as standard transportation monitor in other cases.
Fig. 3 illustrates the elementary cell of an embodiment of transportation monitor 11.The core of monitor is the general measure unit 31 that is configured to obtain from the patient physiological signal data.Measuring unit comprises the magnetic assembly unit, and they make measuring unit inoperative existing under the situation of highfield.No matter the existence of highfield, monitor comprises and reconfigures unit 33 for the monitoring capability that keeps measuring unit at least in part, and it is suitable for reconfiguring monitor, makes to the small part monitoring capability to keep in the highfield.When detecting the highfield, when promptly intensity reached the magnetic field of predetermined threshold value, magnetic field detection unit 32 can be notified and reconfigure the unit.In response to this notice, reconfiguring the unit can be by the whole or selected magnetic assembly unit of forbidding measuring unit and by one or more replacements unit 34,35 is connected to measuring unit, reconfigure monitor, make monitoring when having the highfield, to proceed.Consider operation, reconfigure the unit thereby can be divided into two logical blocks: be configured to forbid the forbidden cell of the magnetic assembly unit of wishing in the measuring unit and the appointment unit (commission unit) of the unitary introducing of one or more replacements that permission is worked in the MRI operator scheme.The unit that comes into operation in the MRI operator scheme may be respectively inner unit 34 or the outside unit 35 of replacing replaced.Reconfiguring the unit also can operate in opposite direction; When detecting unit 32 indication highfields no longer exist, reconfigure the unit can disconnect/disable external/inside is replaced the unit, and is reactivated inner magnet assembly unit, enabling pattern thus.As hereinafter discussing, externally to replace under the unitary situation, measuring unit can comprise the additional interface that is used for the replacement unit is connected to measuring unit.
Though the detection in magnetic field separates with reconfiguring logically of reality, magnetic field detection unit 32 can be embodied as in practice and reconfigures unitary integration section.But, because the automatic detection in magnetic field is optional, and because detection is logically different operations with reconfiguring, so the magnetic field detection unit is ready-made different unit in Fig. 3.
As mentioned above, the magnetic assembly unit typically is used in the measuring unit of blood pressure of transportation monitor.In NIBP (non-invasion blood pressure) unit of transportation monitor, the magnetic assembly unit is typically formed by magnetic pumping and one or more magnet valve.Fig. 4 illustrates and is responsible for the unitary example that the NIBP in the transportation monitor 11 measures.Transportation monitor 11 comprises conventional NIBP unit 40, and the NIBP in the normal manipulation mode of NIBP unit 40 responsible monitors measures.The NIBP unit comprises the control unit 41 of control unitary (pneumatic) pump of NIBP and valve cell 42.Pump and valve cell are connected to the cuff 43 that is attached to object.Pressure transducer 44 is measured the pressure of cuff, and measurement result is offered control unit 41.In standard NIBP unit, pump and valve cell comprise magnetic pumping and magnet valve usually, and they can not use when the transportation monitor is in the highfield of MRI device.
When the transportation monitor was in normal manipulation mode, the operation of NIBP unit 40 was corresponding to the unitary operation of conventional NIBP.In other words, control unit control pump and valve cell are inflated and venting cuff, and determine blood pressure based on the pressure reading that obtains from pressure transducer.
For the MRI operator scheme, NIBP unit 40 is equipped with satellite interface 45, and the flexible pipe 46 of external pump and valve cell 47 can be connected to satellite interface 45.External pump and valve cell can be positioned at the fixed position within the short distance of MRI device, but still enough as far as making magnetic field remain low in described position.In practice, the distance between MRI device and external pump and the valve cell 47 can be for example 3 to 5 meters, to guarantee that externally the place, unit is enough low in magnetic field.External unit also can be outside the MRI chamber.
When making transportation monitor 11 near the MRI device, the magnetic field sensor 32 of monitor detects the highfield.As a result, the NIBP unit enters the MRI operator scheme by forbidding internal pump and valve cell 42.Then, the user of monitor can be connected to the NIBP unit with the flexible pipe 46 of external pump and valve cell.When connecting when ready, control unit is controlled external pump and valve cell according to controlling the similar mode of internal pump and valve cell 42 to it in normal manipulation mode.Control channel between control unit and external pump and the valve cell can be wireless.Therefore, external pump and valve cell are equipped with: be configured to receive the control interface 48 from the control command of the NIBP control unit of the transportation monitor of visit MRI environment, and be used for the pneumatic pneumatic interface 49 that is connected to the unitary satellite interface of NIBP of this type of visit transportation monitor in unit.
Therefore, magnetic field sensor and control unit here form and reconfigure the unit, and it is suitable for reconfiguring monitor, make monitor can keep its monitoring capability in the MRI environment.Monitor also comprises and is used to connect the replacement system, i.e. the pneumatic interface 45 of external pump and valve cell, and the replacement system replaces the magnetic assembly unit of forbidding, i.e. internal pump and valve cell in the MRI operator scheme.Since external pump and valve cell further from the MRI device and thereby be in the downfield, so it can similarly comprise the magnetic assembly with the situation of internal pump and valve cell.
Fig. 5 illustrates the internal pump that includes pump and air bleeding valve in the present embodiment and an example of valve cell and external pump and valve cell 42,47.In normal manipulation mode, 51 pairs of cuff inflations of control unit order internal pump.In the MRI operator scheme, forbidding internal element 42, and external pump and valve cell 47 are connected to the cuff flexible pipe by satellite interface 45.Control unit then orders external pump 53 via 46 pairs of cuff inflations of flexible pipe.In normal manipulation mode, control unit is opened exhaust gas inside valve 52 so that allow cuff deflation, and in the MRI operator scheme, control unit is opened outside air bleeding valve 54 (exhaust gas inside valve 52 cuts out).Pressure transducer 44 is all measured the pressure of cuff in two kinds of operator schemes.
Fig. 6 illustrates another example of internal pump and valve cell and external pump and valve cell 42,47.In this example, suppose that cuff is two flexible pipe cufves.That is to say that cuff is via a flexible pipe inflation and via another flexible pipe venting.In the embodiment of this figure, cuff is via flexible pipe 61 inflations and via flexible pipe 62 venting.In the example as Fig. 5, internal pump is similar substantially each other with valve cell 42,47 to external pump with valve cell, and each unit comprises a pump and two valves now.In normal manipulation mode, control unit 41 order internal pumps 63 are via 61 pairs of cuff inflations of flexible pipe.In the MRI operator scheme, forbidding internal pump and valve cell 42 also hose connectionly is connected external pump and valve cell 47 via two with cuff.Control unit orders external pump 66 via flexible pipe 69 and 61 pairs of cuff inflations then.In normal manipulation mode, control unit is opened exhaust gas inside valve 65 so that allow cuff deflation via flexible pipe 62, and in the MRI operator scheme, and control unit is opened outside air bleeding valve 68 (exhaust gas inside valve 65 cuts out) so that allow cuff deflation via flexible pipe 62 and 69 '.In this embodiment, two pressure transducers 44 are used for measuring the pressure from two cuff flexible pipes.For security purpose, valve 64 and 67 is connected to filling channel.
Except the NIBP unit, standard transportation monitor typically comprises the magnetic assembly in the isolated isolating transformer of so-called patient in the power supply chain that is used for being implemented in monitor.Fig. 7 illustrates the power supply chain of typical transportation monitor.Isolating transformer 73 is divided into two parts with monitor: base part 70 and floating part 71.Base part also can be called non-floating part.Isolating transformer is patient's earth potential, and ground (non-earth ground) promptly unsteady or non-ground connection separates with the earth potential electricity of base part.Suppose in the example of Fig. 7: when the transportation monitor was connected to central patient monitor, central patient monitor provided supply voltage to the transportation monitor.Supply voltage is offered the DC/DC power supply 72 of base part.When the transportation monitor received supply voltage, power supply 72 produced the unitary supply voltage that is used for such as the unitary base part of NIBP.The power supply 74 of floating part receives supply voltage by isolating transformer again, and produces the electric power of the front-end electronics 75 of giving measuring unit 31.In the example of Fig. 7, two parts of monitor all are equipped with rechargeable battery.In normal manipulation mode, that is, and when monitor receives from such as the supply voltage of the external power source of central patient monitor the time 76 chargings of 72 pairs of batteries of power supply, and 77 chargings of 74 pairs of batteries of power supply.When in the MRI pattern, be disconnected to the connection of external power source.Non-floating galvanic electricity pond 76 is then to the power supply of the unit of base part, and the power supply of unsteady battery 77 forward end electronic devices.This situation adopts switch 78 and 79 to illustrate, and wherein adopts position that solid line represents corresponding to normal manipulation mode, and adopts position that dotted line represents corresponding to the MRI operator scheme.
In the example of Fig. 7, power supply and isolating transformer 73 are formed on the magnetic assembly unit of forbidding in the MRI operator scheme, and battery is formed on (inside) replacement unit that comes into operation in the MRI operator scheme.Reconfigure the unit and be included in required switch of conversion between the power supply and the controlling organization that is associated in this case.Because isolating transformer is to need disabled magnetic assembly under every kind of situation when entering the MRI pattern, thus possible be that in another embodiment, power supply 72 keeps working when entering the MRI operator scheme.In this embodiment, thereby omit battery 76, and realize there is not the power supply 72 of magnetic assembly, so that keep the ability that it is worked in the highfield.
The magnetic assembly unit that will forbid can be depending on the structure of transportation monitor.Whether in addition, replace the type of assembly and amount and can be depending on full monitoring capability and will keep in the MRI environment, perhaps whether some physiological datas of record skip to(for) the persistent period of MRI process can be accepted.This equipment also can be equipped with the selection tool that is used for selecting the monitoring function that will keep in the MRI imaging process.Therefore, can forbid inoperative all magnetic assembly units in the MRI environment, and if the limited selection that keeps monitoring capability in the MRI operator scheme is enough, then needn't replace all magnetic assembly units by replacing the unit.
Use above-mentioned mechanism, low-cost transportation monitor can be used to provide patient's the monitoring of not having interruption in fact in the MRI environment.The change that needs in routine transportation monitor is quite little, and thereby cost also remain low.In the MRI environment, need more changes so that be described environment outfit external pump and valve cell 47.But these change is not extensively to need, because typical hospital may only have one or two MRI device.
Realize and change can be depending on to the transformation of MRI operator scheme and the automaticity from the transformation of MRI operator scheme.For example, may not have the automatic detection of highfield, but the user may must manually activate transformation.If use the automatic detection of highfield, cause that then the predetermined threshold of the detection that the highfield is existed can change.Depend on realization, require the quantity of user's manual connection also can change.For example, if described connection is not wireless connections, then the user may must set up the control connection between NIBP unit and external pump and the valve cell.When the user will arrive or leave the MRI environment, monitor also can be indicated the user by variety of way.
This written description usage example openly comprises the present invention of optimal mode, and makes those skilled in the art can make and use the present invention.The scope of patentability of the present invention is defined by claim, and can comprise other example that those skilled in the art expect.If this type of other example has structure or the executive component as broad as long with the literal language of claim, if perhaps they comprise structure or the executive component that has with the non-essence difference of the literal language of claim, then they are intended to fall within the scope of claim.
